代谢

大鼠肝微粒体UDP-葡萄糖醛酸基转移酶和标记的UDP-葡萄糖醛酸与/PR毒素/ P.R.T.或通过体外毒素代谢获得的化合物一起孵化。在相同的条件下，将标记的P.R.T.或其标记的代谢物与UDP葡萄糖醛酸基转移酶一起孵化。使用Eremofortin C和Eremofortin C醇产生了放射性代谢物，在每种情况下，这些代谢物都被鉴定为相应的β-葡萄糖醛酸苷结合物。没有观察到P.R.T.或P.R.T.醇的可测量葡萄糖醛酸化。生物学效应与葡萄糖醛酸苷结合物形成之间显示了良好的相关性。

Rat liver microsome UDP-glucuronyltransferase and labeled UDP-glucuronic acid were incubated with /PR toxin/ P.R.T. or the compounds obtained by in vitro toxin metabolism. Under the same conditions, labeled P.R.T. or its labeled metabolites were incubated with UDP glucuronyltransferase. Radioactive metabolites were produced with Eremofortin C and Eremofortin C alcohol and in each case, were identified as the corresponding beta-glucuronide conjugate. No measurable glucuronidation of P.R.T. or P.R.T. alcohol was observed. A good correlation between biological effects and glucuronide conjugate formation was shown.

毒理性

• 解毒与急救

/SRP:/ 立即急救：确保已经进行了充分的中毒物清除。如果患者停止呼吸，开始人工呼吸，最好使用需求阀复苏器、袋阀面罩装置或口袋面罩，按训练操作。如有必要，执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果发生呕吐，让患者前倾或置于左侧（如果可能的话，头部向下）以保持呼吸道畅通，防止吸入。保持患者安静，维持正常体温。寻求医疗帮助。 /毒物A和B/

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/

/SRP:/ 高级治疗：对于无意识、严重肺水肿或严重呼吸困难的病人，考虑进行口咽或鼻咽气管插管以控制气道。使用气囊面罩装置的正压通气技术可能有益。考虑使用药物治疗肺水肿……。对于严重的支气管痉挛，考虑给予β激动剂，如沙丁胺醇……。监测心率和必要时治疗心律失常……。开始静脉输注D5W /SRP: "保持开放"，最小流量/。如果出现低血容量的迹象，使用0.9%的生理盐水（NS）或乳酸林格氏液。对于伴有低血容量迹象的低血压，谨慎给予液体。注意液体过载的迹象……。使用地西泮或劳拉西泮治疗癫痫……。使用丙美卡因氢氯化物协助眼部冲洗……。 /Poisons A and B/

/SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... .

案例报告/一名在制造蓝纹奶酪的工厂工作的患者对罗克福青霉菌产生了超敏性肺炎。咳嗽、呼吸困难、不适的症状，以及双肺基底湿啰音、肺容积减少、低氧血症和胸部X光片上双侧浸润影的发现，在她离开工作场所后得到了缓解。支气管肺泡灌洗显示淋巴细胞比例较高。血清和灌洗液中均检测到对罗克福青霉菌的抗体。据作者所知，这代表美国奶酪制造行业中新的超敏性肺病发生案例。/罗克福青霉菌/

/CASE REPORTS/ A patient employed in a plant where blue cheese was manufactured developed hypersensitivity pneumonitis to Penicillium roqueforti. Symptoms of cough, dyspnea, and malaise, and findings of bibasilar crackles, reduced lung volumes, hypoxemia, and bilateral infiltrates on chest roentgenogram, resolved after she left the workplace. Bronchoalveolar lavage revealed a high percentage of lymphocytes. Antibody to P. roqueforti was demonstrated in serum and lavage fluid. To /the authors'/ knowledge this case represents a new occurrence of hypersensitivity lung disease in the cheese manufacturing industry in the United States. /Penicillium roqueforti/
